I have a strange smell in my nose and wonder if it could be a chemical sensitivity. It seems to be triggered by smells (exhaust) and lingers for weeks?

In brief: Chemical not likely

The most likely reason for a persistent strange smell is a chronic sinus infection.
Less likely are injuries to the olfactory nerves. Chemical sensitivity is not likely.
